Presentation
Presenting with rectal mass. Proctoscopy suggested malignancy, which was proved histopathologically.
Patient Data
Multiple hepatic hypodense lesions with central dense foci on the non-contrast CT images. These lesions show relative hypoenhancement on the portovenous phase. These features are typical of metastases.
The hyperattenuating foci in the metastases are faint and amorphous, but compatible in this setting with diffuse calcifications.
Case Discussion
Hepatic metastases can take many appearances, including calcified metastases. Calcified metastases are associated with gastrointestinal mucinous adenocarcinomas. In this case, the primary tumor is a colorectal mucinous adenocarcinoma.
HISTOPATHOLOGY
- Moderately differentiated colorectal mucinous adenocarcinoma
